Original Prusa i3 MK2 Alternate Part Cooling Nozzle

An alternate part cooling nozzle I designed for my Prusa Original i3 MK2, hopefully to improve part cooling performance on the back-side of parts. It is currently mounted on my printer, but I have not yet completed enough testing to determine if it really is an improvement, or by how much. Please let me know in the comments how it works for you and I will continue to refine the design.

In order to mount this nozzle, you also require a modified extruder cover, which is listed here: http://ww
